Exactly as described works for Macbook 2017 with USB 3.0. I managed to set up 2 external monitors to my macbook air thanks to this. First screen using the thunderbolt to HDMI and the second one using this USB 3.0 to HDMI converter. There are no delays good picture quality and resolution. Higly recommend it for people looking to link up more than one screen to a mac well worth the money.
